VALVE MECHANISM FOR DISYENSING FLUIDS.

Application filed April 28, 1926. Serial No. 105,186.

r 7 Our invention relates to improvements in valves, and more especially to valves adapt- ;ed to be placed on the end of a hose through which fluids are desired to be passed for dis- Rpensing into containers.

1 .It is a matter of common knowledge that it is e an every day occurrence at filling stations for filling the tanks of automobiles {that the hose and nozzle is withdrawn from the tank before all the gasoline has run from the same into the tank, thus spilling the gasoline over the tank and over parts of the automobile, thus increasing the fire hazards.

It is an object of our invention to make such occurrences impossible.

{ I In the patent to Patrick, Number 1.549,-

500, dated August 11 1925, means are pro- .vided for partially effecting the desired result. This patent issued to the applicants,

and this invention relates to means for more perfectly obtaining the desired result.

In the above-referred to patent the pressure is directly against the head of the valve, and it is an object of this invention, to cause the liquid to press against the side of the valve, thus causing it to operate more easily and efiectively.

1 end of the hose used with the ordinary gasoopen the valve when our device engages the, Portions of the tank on the automobile around the orifice for filling said tank.

Another object of our invention is to provide simple means to be attached to the end of the hose in a gasoline pump ata filling station which will enable the operator to control the flow of gasoline without being in close proximitv to the pump, and at the same time making itimpossible to spill gasoline around the tank.

Another objectof our invention is to provide'.fluid dispensing means in which the 'il'uidenters the dispensing means at an angle to its longitudinal axis, thus holding the device in position in the orifice of the con- Another object of our invention is to providea valve adapted to be attached to the tainer into which the fluid is desired to be dispensed. p

Having thus stated someof the, objectsof our invention, a brief description of one embodiment of our invention is set forthinthe accompanying drawings, in which Figure 1 is a side elevation of our valve. showing in dotted lines the valve and associated parts in raised position; Figure 2 is a longitudinal sectional view taken along the line 2-2 in Figure 2, look 00 mg in the direction indicated by the arrows; Figure 3 is a cross-sectional view of our valve taken along the line 3-3 in Figure, 2, looking in the direction indicated by the arrows;

Figure 4 is a cross-sectional view taken along the line 4-4 in Figure 2, looking in the direction indicated by the arrows. A brief description of the drawings hav mg been given, a detailed description will now follow in which the numeral 10 indi- 'cates the tubular section which has a spider member 11 in its upper interior portion which spider member is integral with, the wall portions thereof. This spider member 7 11 has a perforation 12 in its central portion. On oppositely arranged portions of the walls of the tubular section 10tliere"are,-, the longitudinal slots 18 and 14 in which the pin 15 slides in an up and down manner. A 30 valve 16 is seated in the upper end of the tubular member 10, and said valve has a stem 16' which passes through the perfora-i, tion12 and extends downwardlyinsideof the tubular member 10 and has a hole through its lower end through whichthe pin 15 passes. A compression springl'l' is coiled around the valve stem 16' aridis'heldQ at its ends by thespider 11 and the pin" 15.

Loosely and slidahly encircling the tubu- 1211' section 10 is an annular member 18 which has a circular projection 19aroun'd its upper portion. This annular member 18 has, interiorly threaded holes through its wall portions for the reception of the pin 15, said pin having threads on its ends am enga ernentwith the threads in these holes. e upper end of the tubular member has exterior threads 20 thereon, which are adapted to receive the lower interiorly threaded end or base of the hollow member 21. This member 21 is of approximate Y- shape. and has one of its prongs or hramhes closed at its end. The other branch 22 oi this Y-shaped member 21 has an enlarged open end which has interior threads 23 therein which are adapted to receive the threaded end of the hose member 24. This hose 24 is of the type used at gasoline filling stations for conducting the gasoline from the pump to the tank of an automobile.

It will be noted in ol'iscrving the dotted lines in Figure l that the upper end of the tubular member 10 with the valve 16 projects above the junction point of said tubular member and the open branch of the Y-memher, so that while the valve is closed all of the pressure of the gasoline is not directly on top of the valve. and when the valve is in the open position shown by the dotted lines in Figure 1 there wi l be practically no pressure on the top of the valve. and therefore there will be no tendency on the part of the valve to close while the gasoline is passing therethrough until the pressure on the projection 19 is relieved.

It will be understood that our device is not to be limited in use to dispensing gasoline at filling stations. but mav be used in connection with any means for controlling the dispensing of fluids.

It will also be understood that the shape of our device is an important feature. as this causes the device to remain in an orifice notwithstanding the pressure exerted by the column of fluid in the fluid conducting means.

The method of operation is as follows:

By means of the threads 23 the valve is attached to the hose of a gasoline filling tank. said hose being indicated by the reference numeral 24. The tubular member 10 t is inserted in the opening in the tank on the automobile and the projection 19 will engage the tank on the automobile and the weight of the device together with the weight of the gasoline in the hose 24 will press the annular member upwardlv and will thus open the valve 16 and the gasoline will flow through the valve into the gasoline tank of the automobile until the valve is lifted out of the tank on the automobile, when the valve will automatically close on account of the pressure on the projection 19 being relieved.

It is thus seen that we have devised eflicient means for the controlling of the dispensing of gasoline and other fluids in such a manner as to prevent spilling the same while dispensing.

Having thus described one illustrative embodiment of our invention. we desire it to be understood that although specific terms are employed, they are used in a generic and descriptive sense and not for purposes of ln'mtation, the scope of the invention being :el forth in the. appended claims.
